2/7x+1/2x=40/7-1/6x solve for x

Mathematics
1 answer:
torisob [31]3 years ago
8 0

Answer:

Keeping in mind the 'x' is in numerator, i got the answer to be 6.

Step-by-step explanation:

2/7x + 1/2x = 40/7 - 1/6x

2/7x + 1/2x + 1/6x = 40/7

2/7x + (3+1)/6x = 40/7

2/7x + 4/6x = 40/7

2/7x + 2/3x = 40/7

(2*3)+(2*7) / (7*3)x = 40/7

(6+14) / 21x = 40/7

20/21x = 40/7

20x = 40*21/7

20x = 40*3

x = 40*3 /20

x = 2*3

x=6

Drag the correct factors to the expression. Not all factors will be used. Use synthetic division to find all the factors of this
fiasKO [112]

The factors are therefore;  (4x – 3), (x + 3) and (x – 1)

<h3>What is a polynomial?</h3>

A polynomial is is a function that contains an algebraic term which is raised to a particular power.

  • If it is raised to power 1 it is linear
  • If it is raised to power 2 it is quadratic
  • If its is raised to power 3 it is cubic
  • If it i raised to power 3 it is quartic

Now we have;

4x³ + 5x² – 18x + 9

Thus we can write;

4x³ – 3x² + 8x² – 6x – 12x + 9

Using the factors;

x²(4x – 3) + 2x(4x² – 3) – 3(4x – 3)

Therefore;

(4x – 3)(x² + 2x– 3)

(4x – 3)(x² + 3x – x – 3)

(4x – 3)(x + 3)(x – 1)

The factors are therefore;  (4x – 3), (x + 3) and (x – 1)

Solve algebraically for x: 4-√2x-5) = 1
klemol [59]
Here's how to solve this equation:

4 - <span>√2x-5 = 1
</span><span>√2x-5 = 4-1
</span><span>√2x-5 = 3 (now we have to square both sides to get rid of the root)
</span><span>√2x-5=3  / ^2
</span>(<span>√2x-5)^2 = 3^2
2x-5 = 9
2x = 9+5
2x = 14
x = 14/2
x = 7

The correct answer is 7. </span>
